Meta configuration data schema

meta

Defining vector and raster data layers that should be shown in the appropriate left-hand side menu and might be referred to elsewhere in the configuration file.

More information about what data layers to use can be found here and here.

We also note that all editions require a layer which name starts with '_PLAYAREA', depicting basically the 'bounding box' of all data (literally the play area of the players). More information about that can be found here.

Field	Type	Description
layer_name	string	name of the datalayer, not the display name, but the actual geodata name
layer_geotype	string	Type of Geometry "polygon", "point", "line", "raster"
layer_entity_value_max	float	Optional, representing the highest greyscale (black to white) value of a raster cell. Default is 1000.0, also when set to null. Other logical value is 255.0.
layer_short	string	What is the in-game name of the layer
layer_category	string	What category is this layer part of
layer_subcategory	string	What subcategory is this layer part of
layer_download_from_geoserver	int	Should GeoServer be called to attempt to obtain the layer data (regardless of the type)? 0 for no, 1 for yes (so the int functions as a boolean)
layer_width	int	width of the raster (Not sure if still used)
layer_height	int	Height of the raster (Not sure if still used)
layer_raster_material	string	Name of the shader used for this raster
layer_raster_filter_mode	int	0 or 1, so int functions as a boolean.
layer_raster_color_interpolation
layer_raster_pattern	string	The pattern used by the raster file, this can remain on default most of the tim
layer_raster_minimum_value_cutoff	float	The value where the raster drawing starts, this can be handy if the first part of the raster file should be transparent
layer_active	int	0 or 1, functioning as a boolean. If inactive, then the layer wont be loaded by the server
layer_selectable	int	0 or 1, functioning as a boolean. Can the layer be selected by the player (properties window)
layer_editable	int	0 or 1, functioning as a boolean. Can the layer be edited by the player
layer_toggleable	int	0 or 1, functioning as a boolean. Can the layer be toggled by the player (on/off)
layer_active_on_start	int	0 or 1, functioning as a boolean. Is the Layer on by default when the game starts? (Countries, Bathymetry, EEZ)
layer_green	int	0 or 1, functioning as a boolean. ENERGY: if the layer is uses an energy type in Special Editing then this defines whether it is part of the Green or Grey energy system
layer_tooltip	string	Additional information shown when hovering over a layer in the client windows.
layer_information
layer_media	string	link to the wiki page of this layer. The base URL is set in datamodel > wiki_base_url. The string must always be: "wiki://"+PageName e.g. "wiki://NS_EEZ"
layer_text_info
layer_states	object[]	How long the geometry remains in a specific state
→ state	string	State reference: "Assembly" = construction time, "Active" = time before it is operational, "Dismantle" = time to remove
→ time	int	Time in months the state should last
layer_editing_type	string	Types for Energy (cable, transformer, socket, sourcepoint,sourcepolygonpoint), Multitypes and Protected Areas
layer_special_entity_type	string	Is it a shipping line or not
layer_depth	int	Layering position, the higher the number the further on top (2 = in front of 1)
layer_property_as_type	string	Optional string of the layer geometry feature property that should be read when determining the type, as further defined under layer_type below. Null if irrelevant.
layer_type	object[] (with keys)	Defining which types this particular layer should have (minimum one, first key should always be 0). The keys of this list are referenced elsewhere in the configuration file, notably in MEL > pressures > name and in restrictions > starttype or endtype.
→ displayName	string	The name of the type being defined here that the user will actually see.
→ approval	string	does this layer need to be approved by: EEZ, Region Manager/Admin, All Countries (IMO Routes), or not at all: EEZ, AreaManager, AllCountries, NotDependent
→ value	int	The highest value of a raster cell. Minimum 0, maximum 255 (requiring layer_entity_value_max to be set to 255.0) or 1000 (default, no layer_entity_value_max setting required).
→ map_type	string	Optional, but required when layer_property_as_type is not null, representing the value of the layer's geometry feature property defined under layer_property_as_type that should be mapped to this type. Null if irrelevant. Can be 'other' indicating a 'catch-all' type if none of the other types can be mapped to. Can also be an integer or float/decimal range, without spaces, and using - (dash) as a separator. E.g. 10-20.
→ displayPolygon	int	0 or 1, functioning as a boolean. is the polygon fill displayed (only possible for polygon geometry)
→ polygonColor	string	Hexadecimal colour code (last two digits representing transparency) of the polygon. Has to start with hash #.
→ polygonPatternName	string	pattern used (if the name does not exist, or string is empty, then the default pattern is used)
→ innerGlowEnabled	int	0 or 1, functioning as a boolean. is there an inner glow on the polygon (used for EEZ)
→ innerGlowRadius	int	size of the glow
→ innerGlowIterations	int	strength of the glow
→ innerGlowMultiplier	int	strength of the glow
→ innerGlowPixelSize	int	strength of the glow
→ displayLines	int	0 or 1, functioning as a boolean. are the lines displayed (possible for Poly and Line data)
→ lineColor	string	Hexadecimal colour code (last two digits representing transparency) of the line. Has to start with hash #.
→ lineWidth	int	width of the line
→ lineIcon
→ linePatternType
→ displayPoints		are the points displayed (possible for Point, Poly and Line data).
→ pointColor	string	Hexadecimal colour code (last two digits representing transparency) of the point. Has to start with hash #.
→ pointSize	int	determines the point size, should always be >1, even for Poly and Line data, since this determines the size for the editable points.
→ pointSpriteName	string	sprite used (nothing = regular dot)
→ description	string	short description of the layer type, can be displayed when hovering over the type in the active layer window
→ capacity	int	used for calculations Energy: determines max energy passthrough / production
→ investmentCost	int	costs for planning this type (currently unused, planned to uses for assigning planning points)
→ availability	int	in what year will the type become available, based on the start year of the game (see metadata > start) Always make sure that (for editable layers) the First Type of the layer is available before the game starting date. Otherwise players will be able to edit non-available types, since the system auto-selects the first type for editing.
→ media	string	link to the wiki page of this layer type. The base URL is set in datamodel > wiki_base_url. The string must always be: "wiki://"+PageName e.g. "wiki://Ferry"
layer_info_properties	object[]	Defining what and how feature property data should be shown to the user when clicking on the feature on the map.
→ property_name	string	The feature property present in the data table of this layer's source data.
→ enabled	int	0 or 1 (so integer representation of a boolean) representing whether this feature property should be shown to the user at all.
→ editable	int	0 or 1 (so integer representation of a boolean) representing whether the user should be able to change feature property value. NOT IMPLEMENTED.
→ display_name	string	The name that should replace the original property_name when showing it to the user (requires enabled to be 1).
→ sprite_name	null	NOT IMPLEMENTED
→ update_visuals	bool	Always false, NOT IMPLEMENTED
→ update_text	bool	Always false, NOT IMPLEMENTED
→ update_calculation	bool	Always false, NOT IMPLEMENTED
→ content_type	int	Always 0, NOT IMPLEMENTED
→ content_validation	int	Always 0, NOT IMPLEMENTED
→ unit	null	NOT IMPLEMENTED
→ default_value	string	representing what to show in case the source feature property data's value is null.
layer_tags	string[]	Tags used by Procedural Ocean to determine how to show this layer data and what to enable on it
